How to keep clutch shaft bearings in place?

[tylerlough]

Both the bearings were bad, so I replaced them. I had a heck of a time getting the new bearings in place, I even damaged one in the process. I got them in by heating the case and making the case openings a little bigger. Apparently I made them too big and they want to slide out of place.

Possible solutions:
1. Add a couple of set screws to hold them in.
2. Epoxy them in place.
3. Buy a new case, or used case.

What should I do?

Use loctite sleeve retainer, it's just what the doctor ordered.

Never seen loctite sleeve retainer before, where is it sold?

[Bikeguy Joe]

The auto part store...Permatex also makes it, PX #64040

I have an engine case for a Dax 70cc engine that uses the large studs to hold on the cylinder I'd sell.

Thanks Norman, but I think I got it, I used quiksteel (epoxy putty). Your guides have been very helpful to me. I would have bought the stuff Joe suggested but couldn't find it on AZ's or AAP's sites. Can't wait to get my pocket bike pipe put on. The difficult part is going to be the jetting.

my clutch kind of fell apart on me. Something that would hold in the grease aparantly isn't holding in the grease anymore. Any suggestions where i could find a good guide on how to rebuild the clutch? I have a spare motor that had issues in the head that i could use for parts. thanks guys

This isn't a clutch rebuild procedural guide...but it sure will give you a good idea how the thing is put together.

There is an exploded view at the bottom left of each animation...click it twice and print it out for reference.

THAT IS INSANE!!!! thank you soo much..... now i can't wait for a day off to do it. One last question. I noticed a lot of grease coming from behind the clutch sprocket. So i assume when i do this, i must put some back? any idea how to do that?.... thanks again.... i'm very impressed

Ok... so I have taken the covers off of each side of the clutch... removed the nuts, little washer thing.... and clutch pads... but the sprocket and the parts that hold the clutch pads do not come off.... try to give them a little gentle persuasion... but nothing... any suggestion?
